HOLD CLEANING, HEATING, AND LAMPBLACKING DEVICE.

Application filed March 26, 1924. Serial No. 791,931.

To all whom it may concern:

Be it known that l, ALEXANDER ANDERSON, a citizen of the United States,residing at 9299 Cascade Avenue, Detroit, in the county of Wayne andState of Michigan, have invented certain new and usefullmprovements inMold Cleaning, Heating, and Lamphlacking Devices, of which the followingis a specification.

This invention relates to an improved burner for the uniformdistribution of lamphlacl: upon a series of permanent molds mounted upona rotating table, the said burners being adapted for heating, coolingand cleaning the metal molds. This invention is continuation of myco-pending application, Serial No. 6@l,378, filed September Figure 1shows a cross sectional elevation of the huinertaken on the plane l-1 ofFigure 2. H

rigure 2 shows the application of this burner to the mechanism describedinmy copending application, Serial No. 683,903, filed A ril 23, 1923.

11 Figure l, A is the body of the burner. This burner is cored out andcontains within it the passage B. This passage is provided at C with athreaded entrance which serves as a supporting means for the humor andalso as a conduit thromghwhich the comhustible gas is admitted theburner. The main casting A is also provided with a second entrance Dthrough which the cooling, cleaning and heating gases are admitted.

Outlets E are provided for the cooling, heating and cleaning gases andto these outlets E the nozzles are connected which direct the cooling,heating and cleaning gases aganst the surface of the molds. The coredpassage B connects with the outlets G to which the nozzles H arethreaded. These nozzles H direct the flame of the carbon depositing gasagainst the surface of the molds. A drain plug d is provided in thecasting A for removing any moisture that may he deposited therein fromthe compressed air. I

A flexihle pipe K connects with the entrance to the casting A. A secondflexible pipe connects with the entrance D. @om

pressed air and illuminating gas are supplied through L and acetyleneand air are alternately supplied through K, the air he- 4" ing admittedthrough the pipe and coin trolled by the valve T. A valve M controls thesupply of illuminating gas. A valve N controls the supply of compressedair and the valve O'to the pipe K controls the supply of acetylene.

The casting A is shown suspended by the mechanism described in myco-pending application referred to, which consists of an arm P whichrotates about a center piece Q and rides on an inclined track Y, thetrack Y being supported by the stationary arm S. A roller Z is providedto reduce the resistance to movement. The molds ll V, which are shown inthe open position, carry a proitpcting arm W which contacts with the armThe molds U V rotate about the same center as the piece Q and the arm P.The arm l/V therefore carries the arm P and the casting A with the moldsU V.

The track Y, however, is inclined so that as the molds rotate the arm Pand the casting A are raised until the arm P clears the arm W, uponwhich the casting A and the arm P return to their initial positionsrunning down the inclined track Y and re-engaging with the nextsucceeding molds. The molds U V are carried by the rotating table X uponwhich the molds U V rotate and also move into and out of engagement witheach other.

Operation.-lmmediately [prior to running the machine the valves U and Mare closed, the valve N is opened and the molds are thoroughly cleanedby the compressed air issuing out of the nozzles F. The valve N isalmost closed and the valve M opened, and ordinary city gas ignited inthe burners F. This gas flame is allowed to play on the molds U V untilsuch time as they have reached a suficiently high tem erature, which is500 or 600 F. The to 1e X is then rotated and another pair of molds areheated until all the molds on the table have been heated to the desiredtemperature. The valve M is then closed, the valve 0 is opened and theacetyelene flame allowed to play n the molds U V, the gas issuing st oinozzlhs H. The molds are there ted with lamphlack every time the *ryingthe molds ll V rotates.

event that the acetylene nozzles clogged with lamphlack the valveed,'the valve is o 'encd and the are thus cleaned. rlowever, the airsupplied through T B and till burners H is inadequate for the cleaningof lhe molds and is merely for the purpose described, 7

The metal molds are preferably protected With the coating describedinthe .U. S. Patent #1,453,593, issued to Daniel H. Meloche on the 1st ofMay, 1923.

I prefer not to use the nozzle H for the compressed air and I prefer notto use the nozzle F for the acetylene, for the reason that I have foundit preferable to make the nozzle H in diameter, Whereas the nozzle F mayWell be in diameter as a much greater rate of flow of compressed air orheating gas is desirable than is the desirable flow of acetylene orother lampblack depositing gas.

\Vhat I claim is:

1. In a combined lampblack cleaner and heater, a passage for theadmission of lampblacking depositing gas, a

burner, v

eaaosa separate chamber for the admission of heating and cleaning gases,burners for the heating and cleaning gases, separate burners for thelampblacking gas.

2. A device of the character described comprising a casing having aplurality of passages therethrough terminating in jet nozzles, means foralternately admitting lampblack depositing, heating and cleaning gasesthrough saidpassages to said nozzles.

In a combined lampblack burner,

cleaner, and heater, a passage for the admission of lampblackingdepositing gas, alternative means for admitting compressed air to saidpassage, a separate chamber for the admission of heating and cleaninggases, nozzles for the heating and cleaning gases, separate burners forthe lampblacking gas.

In testimony whereof I affix my signature.

ALEXANDER ANDERSON.
